Optoma UHD38 Bright, True 4K UHD Gaming Projector | 4000 Lumens | 4.2ms Response Time at 1080p with Enhanced Gaming Mode | Lowest Input Lag on 4K Projector | 240Hz Refresh Rate | HDR10 & HLG

Devo instalar na primeira quinzena de janeiro. Só liguei e fiz um teste. Ok

The picture is bright in 4 PM sun with the shades wide open. Of course the darkest colors look even richer with the shades drawn, but it looks 90% just as nice in a bright room (80% as nice with the most strict eco bulb preserving mode). The resolution is true 4K, and it makes a huge difference when you have high-res content. The refresh rate options are nice for gamers with the latest consoles. For blu-ray, the true black is surprisingly deep. The fan noise is somehow quieter than older 1080p models. The audio sound is reasonably clean and loud. However, the lowest setting isn't as low as I'd like to avoid waking someone in the house. Happy surprises: despite having the same familiar remote, the UI is much easier to use than past models, and it's all more responsive too! No more fussing with the source buttons to recognize HDMI signals -- it works the first time, every time. Having the cable inputs in the back looks cleaner than the many side access units out there. Like most projectors, the mounting holes aren't standard. If you're using an arm or ceiling mount, you'll want an adjustable mount on the smallish end (the three holes are roughly 4.5"/4.5"/5” apart in an irregular triangle, longside facing the back). It's long throw. I have around 100" screen at 12.5 ft. (I have to zoom down to fit my 85" screen, and this causes light bleed past the edges.) The zoom range is narrow, like 1-1.1x, so set it up in your house first and try it on a wall before you seek the correct size screen. (Don't be basic using the naked wall; get a screen. The picture quality deserves a good flat white backdrop for all the gorgeous detail.)

I am happy with the projector. The picture is clear even with the ambient light with no distraction. It's just like watching a big100inch TV. The reason for buying this is I don't have a separate room for projection to make it dark as I live in an apartment and during summer times it gets dark very late. Now I watch with out worrying about the ambient light. The picture quality is great with a little compromise on color accuracy due to its high lumens. The picture is more detailed due to its high contrast ratio and most of all I watch it in (eco. mode) where the fan's noise is absolutely quiet which I liked the most as my sitting position is right under the projector. It's easy to operate and the picture resolution gets adjusted automatically as per the source and this is another feature I liked it. I know I am coming there! Yes the gaming mode is quick and the input lag is barely noticeable. Played @1080p120hz the motion is smooth controlling with out blurring just like an instant action on screen. Now I am looking to purchase a PS5 once available and will update the performance after using it. Over all the picture is a decent 4K@60Hz with a pixel shift true 4k colors. The detailing in the picture is very good when watched from certain distance. It has deep blacks. It's a good projector and great alternative for a big TV.

This is my second projector from Optoma, in 2014 I purchased the S316 projector which performed so well for the $309 price point that I when it was time to upgrade I decided to purchase from Optoma again. I purchased the UHD38 to watch movies and eventually play games on. I purchased it on 12/31/2021. Initially there were no major issues with the projector and the image quality was everything that I was expecting. After about 2 months I would notice the occasional color distortion and lines of blocks through the image were highlighted; this issue would come and go and could be reset by reconnecting HDMI link, by April 2022 I had two dead pixels. When my Playstation 5 arrived the projector had issues maintaining connectivity to it via the HDMI port and would constantly disconnect then reconnect which is not ample for gaming. Finally after about 7 months the bulb blew when I was turning the projector off. Now I'm back to using my Optoma S316 which is still operating fine 8 years later. When I attempted to contact customer service by phone I was on hold for about 30 minutes before I left a voicemail with the promise of a return call. The return call never came. So about two weeks after that I searched for the customer service email and I managed to send out an email detailing my problems with the projector. It took thirteen days to get a response by email which included a link to customer support maintenance form. I finally filled out the form today so soon I will see if the projector I spent $1300 on which broke within 7 months is still covered by the warranty. I have no additional recommendations for alternative projectors to purchase at this price point however as it stands right now this project has been rendered unusable with minimal use in a 7 month period, so I do recommend looking elsewhere. I'll update review if projector is repaired by Optoma support and works correctly after fixed, at this point though my expectations are low and I expect that I'm just going to be out the $1300.

Purchased at the end of April of 2022, received and set up in May 2022, picture was great, loading time and lag minimal. Was happy until presumably a fan failed. I have emailed Optoma for support. I hope they will do somthing to back their product. I will update my review once my issue is either resolved or this UDH38 gets sent to the landfill
